KUivrrn TATES GEORGE S. SANFORD, OF MOUNT OLEMENS, MICHIGAN.

CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 481,829, dated August30, 1892.

" Application and November 9,1891. sean No. 411,376. (No modem To allwhom it may concern,.-

.Be it known that I, GEORGE S. SANFORD, a citizen of the United States,residing at Mount Clemens, county of Macomb,State of Michigan, haveinvented a certain new and useful Improvement in Carpet-Sweepers; and Ideclare Jthe following to be a full, clear, and exact descripion of thesame, such as will enable others skilled in the art to which it pertainsto make and use the same, reference being had to the accompanyingdrawings, which form a part of this specification.

This invention relates to carpet-sweepers of the class shown by myseveral applications filed herewith, to wit: Serial Nos. 411,37 3 and411,375, iled November 9, 1891, in the former of which I have shown andclaimed, broadly, the combination of various means for opening andclosing the dust-panwith a rod or cable permanently connected therewithand operating longitudinally with the handle of the sweeper. In thisapplication I desire to cover certain special forms embodying thisprinciple.

In the drawings, Figure lis a sectional view showingthe employment oflevers in conj unct1on with a plunger provided with a coilspring. Fig. 2is a sectional view showing a vertical plunger and a system of levers,one provided with a tooth-segment engagingwth a rock-arm on the side ofthe plunger. Fig. 3 is a sectional view of a construction similar tothat shownin Fig. 1 in which the leveris engaged indirectly with theplunger. Fig. 4 is a view in which the levers employed are on theoutside of the case and the plunger or link extending up through thecase and engaged with a coil-spring on the outside. Fig. 5 isacross-sectional view of the interior of a sweeper constructed accordingto the formV yof one of the rods with the pan being omitted forclearness.

In the drawings, A is the frame or case of the sweeper.

A is the dust-pan.

B is a rock-shaft located longitudinally in the case and rigidlyattached thereto, and close to the inner end of the case is a rockarm B.

B2 isa rock-arm attached to the rock-shaft in the center and extendinginward underneath the opening or in the top of the case, and to theinner end of which is attached a cable C.

D is a vertical rod moving up and down in suitable guides and providedwith a spring d, adapted to force the rod to the extreme upper end ofits movement. The rod D is pivoted at the lower end to the dust-pan AThe action of the spring is to hold the dust-pan in its closed position,and when the cable C is drawn upward by elevating the rock-arm B2 anddepressing the rock-arm B the rodD is depressed and the dust-pan isforced open.

In Fig. 2 the vertical rod or bar is provided with any suitable guide,such as pin d, engaging with the slot d2 in ihe bar or rod, and isprovided with a rack d3, in which is engaged the segment e on the end ofthe lever E. This lever is connected with the rock-arm B by the link b.

In Fig. 3 the construction is similar to that shown in Fig. 1, butemploys a connectinglink F between the vertical rod D2 and the rock-armB.

In Figs. t and 5 the construction is varied from that shown in Figs. 1,2, and 3 in the employment on top ofthe sweeper of a straightlever G,pivotcd to a standard g on the top of the case A, and in which thevertical rod or link D3 is bent or set off to carry its lower end to theside of the sweeper to pivot it to the dust-pan, and is provided abovethe oase with a coil-spring adapted to draw the rod upward and close thedust-pan. In this case the cable or rod C is engaged directly with thelevers outside of the case instead of passing down through the top ofthe case through the opening a.

It is to be understood that in each oE these variations the constructionmay be duplicated to provide for opening and closing two dustpans, andtwo cables or rods running lengthwise of the handle maybe employed, eachconnected with a lever either inside or out- IOO in Fig. 4,pvoted o1'engaged with two Vertical the spring, and means connected with said rodsor standards on the same end of the case rock-arm and extending up thehandle and and adapted to open both dust-pans. movable longitudinallytherewith for operatlVhat I claim is ing the saine, substantially asdescribed. 5 In a carpetsweeper, mechanism for dump- 1n testimonywhereof I sign this specificzii 5 ing the dust-pan, consisting of avertical rod tion in the presence of two witnesses. pivoted at its lowerend to said dust-pan, a GEORGE S.
